, SPECIFICATION forming part of Letters Patent No. 744,902, datedNovember 24, 1903.

Application filed September 5,1903. Serial No. 172,116. (No model.) i

To 60% whom it may concern:

Be it known that I, JOHN F. BUTZ, a citizen of the United States,residing at Fort lVorth, Texas, have invented an Insect-Destroyer, ofwhich the following is a specification.

This invention relates to a device for destroying insects on growingplants, and more particularly to a device or apparatus for destroyingfrom growing cotton-plants the insect known as the boll-weevil, and theobject is to provide an inexpensive apparatus that will effectivelydestroy insects with which plants may be infested.

The objects and various advantages will be fully explained in thefollowing description, and the invention will be more particularlypointed out in the claims.

Reference is had to the accompanying drawings, which form a part of thisapplication and specification.

Figure 1 is a perspective View of the entire device or apparatus. Fig. 2is a vertical crosssection in front of the wheels. Fig. 3 is ahorizontal section of the fume developing chamber and theenveloping-hoods. Fig. i is a rear end elevation of one of theenvelopinghoods.

Similar characters of reference are used to indicate the same partsthroughout the several views.

In carrying out the objects of this invention a box or rectangular boxor chamber 1 is provided,and this boxis mountechpreferably, on twowheels 2 and 3. These wheels are pro vided with an arched axle 4., andthe box is made adjustable as to height on the axle 4 by means ofsuitable bolts 5, so that the box may be adjusted to adapt the apparatusfor plants of various heights. This box is perforated in the front andrear sides for placing perforated hoods 6 and 7 therein. The box hasalso longitudinal slots through thebottom part, sothat the box may bepassed over rows of plants. The hoods 6 and 7 are open at the bottom forthe same reason or purpose. The hoods 6 and 7 close the perforations ofthe box, so that the only escape from the interior of the box is throughthe small perforations in the walls of the hoods. The hoods areperforated, as

shown in Figs. 1 and 3, to allow fumes produced in the box to escapeabout the plants over which the hoods are passing. It is de sirable thatthe fumes remain about the plants long enough to saturate the plantsthoroughly. For retaining the fumes about the plants elongated hoodsSand 9 are mounted in the rear of the box 1 and register with the hoods[5 and 7. The elongated or extension hoods 8 and 9 may be made as longas desirable. The extension-hoods 8 and 9 are supported at the rear endsby means of a frame. This frame consists of the horizontal bars 10 andthe end bar 11, which maybe integral with the bars 10, and the braces 12and 13 and the central brace 14. The extensionhoods S and 9 may be madeof canvas cloth or thin metal or other suitable material. Theseextension-hoods may be attached to the box 1 by means of straps 15 andbuckles 16 and buttons 17 and may be attached to hoops 18 at the rearends by means of buttons 19. The hoops 18 are attached to the bar 11.

j The device may be drawn by one or more horses. The drawings illustratethe device adapted to be drawn by one horse or other animal. Bars 20 areattached to the axle 4 011 top of the box 1 and bent down by the frontof the box and then projected horizontally in front to form shafts 21.14 is bent up to some extent in front of the box 1. A cross-bar 22 isattached to brace 14 and to the bars 20 to brace the shafts. Aswingletree 24 may be mounted on the brace 14.

Means are provided for forcing the fumes to be created in the box 1 toall parts of the box. A fan 25 is mounted on the shaft 26, which may bejournaled in the top of box 1 and in axle 4. Abevel-pinion 27is mountedon shaft 26. A shaft 29 is journaled in bearings 32, and a bevel-gear 28is mounted on shaft 29 and meshes with pinion 27 A sprocket-wheel 31 ismounted on the shaft 29, and a sprocket-chain 30 is mounted on the wheel31 and on a sprocket-wheel 33, which is mounted on the hub of wheel 3,whereby the wheel 33 drives the fan 25 by means of the intermediategearing. Any appropriate fumes for killing insects are created inretorts 34: placed on the bottom of the box 1. The retorts may bedispensed with and the material for creating fumes placed on the bot tomof the box. The fumes may be pro duced by burning material in theretorts or The brace on the floor of the box 1, or the fumes may beproduced by a suitable chemical process. The fumes will rise up in thebox 1 and the fan when driven will distribute the fumes to all parts ofthe box about the hoods 6 and 7, and the fumes will escape through theperforations of these hoods and envelop the plants as the hoods arepassed over the plants. The fumes will be held about the plants for sometime by the extension-hoods 8 and 9. The fumes to be used must beselected according to the kind of insect to be suffocated and the kindof plant to be treated.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An insectdestroyer comprising a wheeled box perforated in the front.and rear sides,

- means for creating and causing suffocatingfumes to circulate aboutsaidhoods and pass from said box through the perforations of said hoods.

v 3. An insect-destroyer comprisingawheeled box perforated in the frontand rear sides, perforated hoods extending through said box and closingthe perforations thereof, said hoods having slots in the lower partsthereof whereby said hoods are adapted to pass over and about growingplants, and means for causing suffocating-fumes to pass out of said boxthrough the perforations of said hoods as said hoods are passing overthe plants.

4. Aninsect-destroyer comprising a wheeled box perforated in the frontand rear sides, perforated hoods extending through said box and closingthe perforations thereof, means for creating suffocating-fumes in saidbox and causing the same to escape through the perforations of saidhoods, and extension-hoods attached to said box and registering withsaid perforated hoods.

5. A11insect-destroyercomprisingawheeled truck having an arched axle, abox adjustably mounted on said axle, said-box being perforated throughthe front and rear sides, perforated hoods extending through said boxand closing said perforations, and means for causing suffocating-fumesto pass from said box through the perforations of said hoods.

6. An insect destroyer having a wheeled truck provided with an archedaxle, a box supported by said axle, perforated hoods extending throughsaid box thereby adapting said box to pass over and about growing plantsas said truck is driven,extension-hoods attached to said box andregistering with said perforated hoods, and a frame braced on said axlefor supporting said extension-hoods.

7. An insect -destroyer having a wheeled truck provided with an archedaxle, a box supported by said axle, perforated hoods extending throughsaid box, means for creating suffocating-fumes in said box, and meansfor causing said fumes to envelop said hoods and escape through'theperforations thereof consisting of a rotary fan and suitable gearingoperatively connecting said fan to one of the wheels of said truck.

In testimony whereof I set my hand, in the presence of two witnesses,this 29th day of August, 1903.

JOHN F. BUTZ.
